How many district composite numbers can be formed by adding 2 of the first prime numbers?
The first two prime numbers add up to another prime number.
What 2 prime numbers add together to make 91?
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
What three prime numbers add up to another prime number?
5 + 7 + 11 = 23
If you add a prime number to itself is the the sum composite or prime?
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
Are prime numbers closed under addition?
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
If you add two prime numbers together what do you get?
You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)

Can you add two prime numbers to make another prime number?
Yes as for example 2+5 = 7
What three numbers add up to a prime number?
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
What three prime numbers add up to another prime number?
5 + 7 + 11 = 23
What three pairs of prime numbers below 12 can you add to get another prime number?
2 and 3 2 and 5 2 and 11
What 2 prime numbers add to make 1.32?
When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
Why is there an infinite number of prime numbers?
Numbers never end. You can always continue to add another digit to a number and make it larger. Because this is the case, you can continue to look forward forever for prime numbers. The difference/distance between the numbers may grow, but prime numbers will continue to appear.
Does two prime numbers always add up to an even number?
No, they do not. If one of the prime numbers is 2, you will have an odd number.
If you add or subtract using only prime numbers is the answer always a prime number?
No, as all prime numbers are odd, excluding 2, and when you add two odd numbers you get an even number. This even number can't be a prime number as it will be divisible by 2. 101 and 31 are both prime, but 101+31 is 132.
Is there an Infinate number of prime numbers?
The number or prime numbers in infinite. Prime numbers can only be divided by 1 and the prime number itself. If you multiply all known prime numbers (you must not leave out any of them) and add 1 to the product the result is another prime number. E.g. 2 * 3 + 1 = 7 (prime) 2 * 3 * 5 + 1 = 31 (prime) 2 * 3 * 5 * 7 + 1 = 211 (prime) ... infinity
